Research on application and security protection of Internet of Things in Smart Grid

The Internet of Things (IoTs) has been considered one of the very promising technologies for the implementation of Smart Grid. First, main features of information and communication systems in Smart Grid are abstracted; the applications of IoTs in Smart Grid are analyzed and classified based on the different function. Then, based on the characters of smart grid systems, reference architecture for Smart Grid IoTs is introduced. Second, main security issues and information security protection requirements of Smart Gird IoTs are well studied. Considering the function of the IoTs application, IoTs in smart grid are classified into three areas with different importance, including electrical industrial control IoTs; gird information collection and process IoTs, and IoTs for power consumer interaction. And classified protection framework of internet of things security is described. The proposed framework can guide the security deployment for Smart Grid IoTs applications. Finally, trusted secure access control system for IoTs terminals is designed for the security protection of Internet of Things in Smart Grid.
